Start by recognizing that the equation is in the form of an exponential equation: \(100^x = 10^{x+17}\).
Express both sides of the equation with the same base. Note that \(100 = 10^2\), so rewrite the left side as \((10^2)^x = 10^{2x}\).
Now the equation becomes \(10^{2x} = 10^{x+17}\).
Since the bases are the same, set the exponents equal to each other: \(2x = x + 17\).
Solve for \(x\) by subtracting \(x\) from both sides to get \(x = 17\).
